Document Type and Number:
WIPO Patent Application WO/2023/035922
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of amplifiers, and in particular, to a power amplifier architecture, a control method, a circuit board, and a controller. The power amplifier architecture comprises a power division network, a first main circuit amplifier, a second main circuit amplifier, an auxiliary circuit amplifier, a combiner, and a main circuit side impedance converter. A first output end of the power division network is connected to an input end of the first main circuit amplifier, and a second output end of the power division network is connected to an input end of the second main circuit amplifier; an output end of the combiner is connected to a first end of the main circuit side impedance converter, and a second end of the main circuit side impedance converter is connected to a load; a third output end of the power division network is connected to an input end of the auxiliary circuit amplifier, and an output end of the auxiliary circuit amplifier is connected to a second end of the main circuit side impedance converter.
